Environmental emission and consumption of energy resources now a day have received substantial attention so far as global sustainable development is concerned. In this regard, purpose of the present book is to investigate general equilibrium implications of international trade and globalization over environmental emission , pattern of energy consumption and social welfare for the Indian economy and recommend necessary policy actions. Computable General Equilibrium(CGE) modelling has been applied as the relevant methodology for the analysis, following Shoven and Whalley (J Econ Lit XXII:1007-1051, 1984). Constructing energy/environmental Social Accounting Matrix (SAM) for India, study examined the effects of liberalized trade over different macroeconomic aspects, energy consumption and green house gas emission through an environmental CGE model logically based on SAM.Attempts have been made to simulate various trade related policies like import liberalization, foreign capital inflow and use of energy saving technologies for examining the impact over macroeconomic variables and domestic physical environment under both perfect and monopolistic competition market structure.
